Liberator advertisement from during the war.

Looks like a master die maker and his apprentice making a combustion chamber core.

Die and core for a combustion chamber.

A master die maker at work. The aluminum foundry was one of the few factories to have it's own die shop "in-house".

This looks like one of the early test molds because of the crude way they are doing it. This could even be at factory #70 where the training took place early in 1942.

These wires were what kept the delicate cooling fins made of sand from collapsing during the molding process. After all the wires were in place, the rest of the mold was filled until it was flush.

The workers became very fast at inserting all the hundreds of wires for each mold.

Putting a finished mold together.

Compressing a new core. You always needed the other half of the mold.

Compressing a new core.

Making the new cores.

Making the cores before baking in the special ovens.

Just as any other casting, there was usually more than one part needed to make up the cavities.

Working on a special inner core. It took a lot of trial and error to get things right.

Inner cores made up.

Making a mix. Aluminum scrap could only be re-melted a few times before it was as brittle as glass when cured.

Slag removal.

Making ingots.

Making the aluminum ingots, so you had a precise amount ready for each pour.

Freshly made molds will be lined up for easy pouring.

Making a pour.

Filling another ladle.

The pouring of aluminum was a very precise operation. It had to be just the right temperature and consistency. It poured like syrup which was nothing like pouring iron.

This is where the ladle was placed between pours.

Opening another mold.

Opening a newly made head. In the early beginnings of this operation, you never knew what would be inside. Once they got all the heat cycles and such right, they were turned out by the thousands. The total was 3,120,000 to be exact.
